Okay, by adding the Shareaholic code to the Default Header section under HTML Includes, the code shows up in the footer.
I would prefer it show about the Reply box....
Did you not add the code in the actual shareaholic field?
Just a question why you chose the default header.
To add it to a reply box you probably need to hack the template for it.
Again I suggest look at the mod at ubbdev.com for suggestions.
Even though that version supports it.
